<![CDATA[Automatic system is a process to control the operation of an a tool that can automatically replace the role of humans. One of the industries that is also experiencing rapid progress is in the field of parking (Smart Parking) for vehicles, both two-wheeled and four-wheeled vehicles. The current parking system still uses a lot of conventional parking systems that only utilize parking lots and parking attendants who control each incoming vehicle and also often do not pay attention to the capacity of the parking lot owned by a building. The research describes a design to build a parking prototype to make it easier for drivers to find empty parking slots. The tool that will be built will start when the car enters the parking area and is detected by the TCRT-5000 sensor, then the servo opens the gate at the command of the Arduino and the driver looks for an empty parking lot. The driver can see the empty parking slots through the parking application that is connected to the database through the Esp 8266 NodeMcu. The LCD will issue an output in the form of letters and numbers.]]>

<![CDATA[Many people are shopping in supermarkets so that baskets and trolleys are usually provided to carry groceries, resulting in frequent cases such as missing or confused baskets. As a result of these problems, a new method is needed in dealing with the problem of swapping shopping cart trolleys. This study describes information about automatic customer follower trolley robots based on image processing and microcontrollers. The design of this control system uses an Arduino Pro Mini Microcontroller which is connected to GPS, Ultrasonic sensors, ESP 8266, and DC motors. Ultrasonic Sensors, The author's purpose is to make research on this trolley robot to make it easier and more comfortable for supermarket customers to shop and carry their groceries, where the trolley is made to be able to follow the user's movements without the need to push it so that customers just have to choose the items they buy and customers can walk in front of their shopping trolleys. The additional devices needed to move the trolley automatically include cameras, microcontrollers, DC motors, servo motors, motor drivers, and batteries mounted on the trolley. Image processing uses a camera on a system that is made to work by detecting the color of the object that has been determined to determine the distance of the object from the trolley. The method used to process image processing is a hue-based color filtering algorithm. So that in its use the trolley is able to move automatically following the customer. The final result of this automatic follower trolley design is a success rate of 80% with the maximum distance between the object and the trolley is 5.65m.]]>

<![CDATA[Steganography is an art and study of invisible communication from confidential data on a multimedia carrier such as image, audio and video files. The most popular steganography method is the LSB (Least Significant Bit) method. However, the LSB method is very vulnerable to attack using basic image processing operations. In 2013, Jassim applied the Five Modulus method in the steganography process. The Five Modulus method will solve a digital image into a set of image subblocks called n x n sizes. Secret messages will be inserted in the window. According to Jassim, the smaller the window size, the more secret messages can be inserted into the image. The resulting steganography software can hide confidential data into a digital image. Secret data stored in the stego image can be extracted out in the extraction process]]>

<![CDATA[The performance of a synchronous reluctance motor (SynRM) depends on the direct axis inductance (Ld) and the square axis inductance (Ld) of the machine. To achieve a high torque density and power factor, increasing the saliency ratio Ld/Lq and making this inductance difference (Ld-Lq) large enough is a well-known method. Otherwise, the performance of the motor will remain below that of a similar induction engine using a similar stator. This study attempts to place the right amount of permanent magnet in the rotor in the right position, it will be possible to achieve a significant increase in the performance of permanent magnet-assisted SynRM (PMa-SynRM) which will be comparable to an induction machine with the same stator. The PMa-SynRM will benefit from the reduction in price due to the use of a conventional induction machine stator.]]>

<![CDATA[In Perwakilan BPKP Provinsi Riau, before official work travel, the officer needs to prepare some documents such as Assignment Letter and Cost Sheet, while the Administrator should make Official Work Travel Letter and Treasurer Accountability Report. To make all the documents the officer has to use other work unit application, and it needs some prodecures to be done that makes the process ineffective and inefficient. Other than that there is no application to monitor the budget yet. So we create a web based application that called Aplikasi Sistem Informasi Keuangan (ASIK) which use waterfall method. Result of the research is documents that needed in official travel can be made faster with ASIK so performance of every officer can be more effective and efficient. Also, with ASIK, leader and administrator can monitor the budget easily.]]>
